Abstract
Description
Möbeloberflächen oder Verkleidungen und Verzierungsteile werden häufig mit einer Dekorschicht, beispielsweise einem Holzfurnier, versehen, um das gewünschte Erscheinungsbild zu erreichen. Die Dekorschicht wird anschließend in aller Regel mit einer Beschichtung versehen, die die Dekorschicht vor Beschädigungen schützt und ihre Struktur hervorhebt. Als Beschichtung kommen insbesondere Lacke in Frage, die auf die Dekorschicht aufgetragen oder ausgesprüht werden. Auch Folien können als Beschichtung aufgebracht werden. Zur Herstellung der Oberflächenveredelung der Möbel oder Verkleidungsteile sind somit zwei Arbeitsschritte erforderlich, das Aufbringen der Dekorschicht und anschließend die Herstellung der Beschichtung beispielsweise durch Lackieren. Weisen die Möbel oder Verkleidungsteile eine kompliziertere räumliche Struktur auf, so gestalten sich diese Arbeitsschritte relativ zeitaufwändig.Furniture surfaces or trim and ornamental parts are often provided with a decorative layer, such as a wood veneer, to achieve the desired appearance. The decorative layer is then usually provided with a coating that protects the decorative layer from damage and highlights its structure. As a coating, in particular paints come into question, which are applied to the decorative layer or sprayed. Also films can be applied as a coating. To produce the surface finishing of the furniture or trim parts thus two steps are required, the application of the decorative layer and then the production of the coating, for example by painting. Do the furniture or trim parts mean a more complicated one spatial structure, these steps are relatively time-consuming.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit zu schaffen, Gegenstände auf rationelle Art mit einem gewünschten Oberflächenüberzug versehen zu können.The present invention has for its object to provide a way to provide objects in a rational way with a desired surface coating can.
Die Aufgabe wird mit einem Halbzeug zur Herstellung von Oberflächenüberzügen, insbesondere für Möbel, Verkleidungs- und Verzierungsteile, gelöst, mit einer Dekorschicht, insbesondere einem Holzfurnier, und einer die Dekorschicht auf der Sichtseite mindestens teilweise abdeckenden Beschichtung, wobei die Dekorschicht und die Beschichtung fest haftend miteinander verbunden sind und das Halbzeug insbesondere durch Zufuhr von Wärme entsprechend der Kontur des zu überziehenden Gegenstandes formbar ist.The object is achieved with a semifinished product for the production of surface coatings, in particular for furniture, trim and decorative parts, with a decorative layer, in particular a wood veneer, and a coating on the visible side at least partially covering the decorative layer, the decorative layer and the coating firmly adhering are interconnected and the semifinished product, in particular by supplying heat according to the contour of the article to be coated is malleable.
In dem erfindungsgemäßen Halbzeug sind die Dekorschicht und die diese abdeckende Beschichtung bereits zu einer Einheit zusammengefügt. Die Verbindung von Beschichtung und Dekorschicht kann bei dem Halbzeug ohne Rücksicht auf die Kontur des zu überziehenden Gegenstandes einfacher und kostengünstiger erfolgen als am zu überziehenden Gegenstand selbst. Handelt es sich bei dem zu überziehenden Gegenstand um einen dreidimensionalen Körper, so lässt sich das Halbzeug entsprechend der Kontur des Gegenstandes formen, wobei der Gegenstand selbst als Form dienen kann und gleichzeitig mit dem Formen des Halbzeugs auch die Verbindung mit dem Gegenstand beispielsweise durch Verkleben oder thermisches Verpressen hergestellt werden kann.In the semi-finished product according to the invention, the decorative layer and the coating covering it are already joined together to form one unit. The combination of coating and decorative layer can be made easier and less expensive in the semifinished product without regard to the contour of the object to be coated than on the article itself. If the object to be coated is a three-dimensional body, then the semifinished product can be correspondingly Shape contour of the object, the article itself can serve as a mold and simultaneously with the molding of the semifinished product and the connection with the object can be made for example by gluing or thermal compression.
Insbesondere wenn mehrere unterschiedlich geformte Gegenstände mit dem gleichen Oberflächenüberzug versehen werden sollen, lohnt sich die Verwendung eines erfindungsgemäßen Halbzeugs, aus dem dann die Überzüge für die einzelnen Gegenstände hergestellt werden können.In particular, if several different shaped objects to be provided with the same surface coating, it is worth the Use of a semifinished product according to the invention, from which then the coatings for the individual objects can be produced.
Als Beschichtung des Halbzeugs kommen wie bei den herkömmlichen Oberflächenüberzügen auch verschiedene Materialien infrage. Vorzugsweise kann die Beschichtung eine Lack-, Kunststoff- oder Kunstharzschicht aufweisen.As a coating of semi-finished as well as the conventional surface coatings also different materials in question. The coating may preferably have a lacquer, plastic or synthetic resin layer.
Die Beschichtung kann auch unter Verwendung eines unter UV-Bestrahlung aushärtenden Materials hergestellt sein. Dies ermöglicht die Herstellung der Beschichtung auch in einem Gießverfahren,The coating may also be made using a UV-curable material. This allows the production of the coating also in a casting process,
Die Beschichtung kann zunächst in flüssiger Form aufgebracht werden oder aber auch bereits als Folie vorliegen, die mit der Dekorschicht verbunden wird.The coating can initially be applied in liquid form or else already be present as a film, which is connected to the decorative layer.
Damit die Dekorschicht optimal zur Geltung kommt, ist es von Vorteil, wenn die Beschichtung transparent ist. Auch die Dekorschicht kann jedoch prinzipiell transparent sein, wenn die Oberfläche des zu überziehenden Gegenstandes noch sichtbar und durch die Dekorschicht beispielsweise nur im Farbton verändert werden soll.To make the decorative layer look its best, it is advantageous if the coating is transparent. However, the decorative layer can in principle be transparent if the surface of the object to be coated is still visible and should be changed by the decorative layer, for example, only in the color.
Durch eine entsprechende Oberflächengestaltung der Beschichtung können zusätzliche optische Effekte erzielt werden. So kann die Beschichtung beispielsweise eine glatte oder strukturierte, insbesondere eine matte, aufgeraute oder geriffelte Oberfläche aufweisen.By an appropriate surface design of the coating additional optical effects can be achieved. For example, the coating may have a smooth or structured, in particular a matt, roughened or corrugated surface.
Bei besonders dünnen oder empfindlichen Dekorschichten ist es weiter von Vorteil, wenn die Dekorschicht auf einem Trägermaterial, insbesondere einem Gewebe, aufgebracht ist.For particularly thin or delicate decorative layers, it is also advantageous if the decorative layer is applied to a carrier material, in particular a fabric.
Das Trägermaterial kann jedoch auch durch das Beschichtungsmaterial gebildet sein. Auch dadurch lässt sich die Stabilität des Halbzeugs insgesamt erhöhen.However, the carrier material may also be formed by the coating material. This also makes it possible to increase the stability of the semi-finished product as a whole.
Bei einer bevorzugten Ausgestaltung kann das Halbzeug je nach seiner Dicke und seiner Flexibilität als flächige Platten-, Blatt- oder Bandware herstellbar sein. Diese relativ großformatige Herstellung des Halbzeugs ist kostengünstig und ermöglicht eine einfache Handhabung des Halbzeugs in der Weiterverarbeitung zu einem Oberflächenüberzug.In a preferred embodiment, the semifinished product, depending on its thickness and its flexibility as a flat plate, sheet or tape product can be produced. This relatively large-scale production of the semifinished product is inexpensive and allows easy handling of the semifinished product in the further processing to form a surface coating.
Zur Formung des Halbzeugs entsprechend dem zu überziehenden Gegenstand kommen verschiedene Verfahren in Betracht. Bevorzugt kann das Halbzeug durch Heißpressen oder Tiefziehen formbar sein, wenn dreidimensionale Gegenstände überzogen werden sollen. Diese Verfahren lassen sich auch mit dem Verbinden des Halbzeugs mit dem zu überziehenden Gegenstand kombinieren. Dieses Verbinden kann beispielsweise mittels einer Verbindungsschicht, durch Verkleben und/oder Verpressen oder durch einen Tiefziehvorgang erfolgen.For the formation of the semifinished product according to the object to be coated, various methods come into consideration. Preferably, the semi-finished product can be formed by hot pressing or deep drawing, when three-dimensional objects are to be coated. These methods can also be combined with the joining of the semifinished product with the object to be coated. This bonding can be done for example by means of a bonding layer, by gluing and / or pressing or by a deep-drawing process.
Es ist allerdings auch möglich, das Halbzeug so auszugestalten, dass es auf der der Beschichtung abgewandten Seite mit Kunststoff hinterspritzbar ist und der Kunststoff eine Verbindung zum zu überziehenden Gegenstand oder den zu überziehenden Gegenstand selbst bildet. Bildet der Kunststoff den Gegenstand selbst, so übernimmt das vorgeformte Halbzeug letztlich die Funktion einer Gießform für den Gegenstand.However, it is also possible to design the semifinished product in such a way that it can be back-injected with plastic on the side facing away from the coating and the plastic forms a connection to the article to be coated or to the article to be coated. If the plastic forms the article itself, then the preformed semi-finished product ultimately assumes the function of a casting mold for the article.
Prinzipiell lassen sich die erfindungsgemäßen Halbzeuge in beliebigen Dicken herstellen. Bevorzugt weisen sie jedoch eine Dicke von 0,8 mm bis 3 mm auf. Dabei kann die Beschichtung vorzugsweise eine Dicke von 0,3 mm bis 0,8 mm aufweisen.In principle, the semi-finished products according to the invention can be produced in any thickness. However, they preferably have a thickness of 0.8 mm 3 mm up. In this case, the coating may preferably have a thickness of 0.3 mm to 0.8 mm.
Bei einem ersten erfindungsgemäßen Verfahren zur Herstellung eines erfindungsgemäßen Halbzeugs werden ein flächiges Dekorschicht-Material und ein flächiges Beschichtungsmaterial, von denen mindestens eines thermoplastisch ist, übereinander gelegt und unter Wärmeeinwirkung miteinander verpresst. Das thermoplastische Material wird dabei zumindest angeschmolzen und bildet nach dem Erstarren eine fest haftende Verbindung mit der anderen Schicht.In a first inventive method for producing a semifinished product according to the invention a flat decorative layer material and a sheet-like coating material, at least one of which is thermoplastic, superimposed and pressed together under heat. The thermoplastic material is at least fused and forms after solidification a firmly adhering compound with the other layer.
Für eine besonders rationelle Fertigung eines dünnen flexiblen Halbzeugs können dabei das Dekorschicht-Material und das Beschichtungsmaterial als Bahnen übereinander liegend in eine beheizbare Presse eingeführt werden. Das Halbzeug mit der fest auf der Dekorschicht aufgebrachten Beschichtung verlässt die Presse dann als Bandware, die entweder aufgerollt oder durch einen Stanz- oder Schneidvorgang in blattförmige Einzelteile zertrennt werden kann. Bei diesem Verfahren kann die Beschichtung zweckmäßigerweise aus einer Kunststofffolie hergestellt werden.For a particularly efficient production of a thin flexible semifinished product, the decorative layer material and the coating material can be introduced as webs lying one above the other in a heatable press. The semifinished product with the coating applied firmly to the decorative layer then leaves the press as a strip product, which can either be rolled up or cut into sheet-like individual parts by means of a punching or cutting process. In this method, the coating can be conveniently prepared from a plastic film.
Nach einem zweiten erfindungsgemäßen Verfahren zur Herstellung eines erfindungsgemäßen Halbzeugs wird eine Dekorschicht oder eine auf einem Trägermaterial angeordnete Dekorschicht in eine Gießform eingelegt oder mit einer solchen verspannt, derart, dass mindestens zwischen der Sichtseite der Dekorschicht und der Gießform ein Hohlraum entsteht, in den flüssiges Beschichtungsmaterial eingefüllt und anschließend ausgehärtet wird. Dieses Verfahren ermöglicht die Herstellung einer sehr homogenen Beschichtung ohne Einschlüsse. Je nach Gestaltung der Oberfläche der Gießform erhält die Beschichtung eine glatte oder strukturierte Oberfläche. Zur Beschleunigung des Verfahrens und zur Vermeidung des Entstehens von Gasblasen in der Beschichtung kann das Beschichtungsmaterial in den Hohlraum eingepresst werden. Zusätzlich oder alternativ kann der Hohlraum vor dem Einfüllen des Beschichtungsmaterials evakuiert werden. Auch dadurch wird das rasche und gleichmäßige Ausfüllen des Hohlraums und die Vermeidung von Gasblasen unterstützt.According to a second inventive method for producing a semifinished product according to the invention, a decorative layer or arranged on a support material decorative layer is inserted into a mold or braced with such that at least between the visible side of the decorative layer and the mold, a cavity is formed in the liquid coating material filled and then cured. This process makes it possible to produce a very homogeneous coating without inclusions. Depending on the design of the surface of the mold, the coating receives a smooth or structured surface. To speed up the process and to prevent the formation of gas bubbles in the coating, the coating material can be pressed into the cavity. Additionally or alternatively, the cavity may be evacuated prior to filling the coating material. This also supports the rapid and uniform filling of the cavity and the prevention of gas bubbles.
Als Beschichtungsmaterial eignen sich für dieses Verfahren flüssige Materialien, die physikalisch oder chemisch aushärten. Bevorzugt kann als Beschichtungsmaterial ein flüssiges Kunstharz eingefüllt und anschließend einer UV-Strahlung ausgesetzt und dadurch ausgehärtet werden. Solche unter UV-Strahlung aushärtenden Kunstharze können beispielsweise Kunstharze auf Polyurethan-, Polyester- oder Acrylbasis sein.Suitable coating materials for this process are liquid materials which cure physically or chemically. Preferably, a liquid synthetic resin can be filled in as the coating material and then exposed to UV radiation and thereby cured. Such UV curing resins may be, for example, polyurethane, polyester or acrylic based resins.
Nachfolgend wird ein bevorzugtes Ausführungsbeispiel eines erfindungsgemäßen Halbzeugs sowie zweier Verfahren zu seiner Herstellung anhand der Zeichnung näher beschrieben.Hereinafter, a preferred embodiment of a semifinished product according to the invention and two methods for its production will be described with reference to the drawing.
